I disagree. Dogecoin has the backing of one of the strongest communities on the internet. It's quite feasible to see it as a virtual currency used to pay for online goods, such as karma, games, or media.

It's friendliness means it may be adopted by the majority of consumers, who are scared off by the volatility and high price of bitcoins.

What needs to happen? First, it needs to distance itself from the meme part of it, and just become the standard fun, digital currency. Second, the barriers to entry need to be reduced. That means buying DOGE with USD instead of bitcoins, and easy online wallets. Finally, it needs uses, the most likely to happen are inter-app payments, such as over reddit or imgur.
